Constants I Periodic Table â¼ Part A Hess's law states that "the heat released or absorbed in a chemical process is the same whether the process takes place in one or in Calculate the enthalpy of the reaction 2N0(g) + O2 (g) â2NO2 (g) several steps. it is important to recall the following rules given the following reactions and enthalpies of formation 1. When two reactions are added, their 1.1 N2(g) +02(g)âNO2(g), Î 2.1 N2(g)+1O2(g)âNO(g), Î Express your answer with the appropriate units. =33.2 kJ =90.2 kJ enthalpy values are added 2. When a reaction is reversed, the sign of its enthalpy value changes. 3. When the coefficients of a reaction are multiplied by a factor, the enthalpy value is multiplied by that same factor View Available Hints) AH Value Units
